I'm working in the data frame, except I've flattened the array for some reason. So the standard bad behavior can be seen in module 6, pixel 7777 in my ntuple:
>>> 96*4
384
>>> 7777/384
20
>>> 7777%384
97
so [6, 20, 97] and all around there.
I see somewhat ok behavior in [14, 20, 97].
[2, 20, 97] and [10, 20, 97] seem plain ok.
[6, 4, 117] looks bad. [2, 4, 117] seems ok.
[10, 218, 53] is pathological in a check-mark way.
[2, 286, 207] is pathological in a check-mark way.

Here are some pixels which are problematic in (calibrated) AML-L in module 6 in both water and air scatter for the limited events I scanned in mfxp175 run 108 and mfxc00118 run 190, respectively:
module row col nBadWater nBadAir
6 175 172 21 150
6 176 107 116 174
6 156 191 25 174
6 268 177 161 150
6 175 161 25 155
6 95 191 21 108
6 93 69 183 508
6 175 180 30 202
6 175 185 24 149
6 175 186 27 196
6 168 191 23 159

Summary
- Minor detector damage is observed in a few constant types - in charge injection gains for FL, AHL-L, AML-L
- Charge injection gains in stead of uniform constant gains can be used to eliminate this effect.
